Adobe xD Booking App

I agree with the last commenter, as an option you can try WordPress or Wix if you want to base the application on the structure application for online hotel booking, then read the article for a description of the required functions. But it seems to me that you should determine for yourself what functions you should have in your application and analyze your competitors. If you cannot do this as an option, you can use freelance or outsourcing services

Adobe XD is only quick prototyping software, and cannot be used to actually develop or build anything. It's just a visual tool for user interface design. That's it.

To create a booking system requires either very good front-end and back-end programming skills, or you have someone build it for you.

Adobe has no tools which automate this in any way. Alternatively, you could install WordPress on your hosting space, buy a good booking plugin for it, and install it on your website.

But this also requires a bit of technical skill, and based on your question I would advice you to hire someone to do this for you.

If your existing beauty salon website is already WordPress based (and there is a good chance it is), then you only need to do some online research to find a good booking app, or just install a form plugin and build a booking form.

Just out of the blue without great knowledge of the products:

For any application you need:

• a user interface (front-end) that knows how to interact with the user(s).
• a data structure (back-end) that is able to store your data that you get from the users and that let you retrieve data to be shown on the user interface.

XD helps building the front-end. The backend still needs to be taken care of.
